1'0 ctZZ whom it may concern.-

Be it known that I, WlLLIAM A. HUTSON, a citizen of the United States,and a resident of- Orlando, in the county of Orange and State ofFlorida, have invented an Improved Car-Replacer, of which the followingis a specification.

My invention is an improvement in the class of car-replacers consistingof a portable device, commonly called a frog or shoe, which is adaptedto be placed over or beside a track-rail and has a grooved and slopingguideway in which a truck-wheel of a railroad-car may .run and be at thesame time guided into due normal position upon the rail.

My invention includes two frogs or shoes,

which are used together, but differ in construction, the same coactingin such way as to replace a car-truck in a novel and expeditious manner.

In the drawings, Figure 1 is a plan view of a section of a railway-trackw ith my improved car-replacer applied thereto. Fig. 2 is a verticalcross-section on the line 2 2 of Fig. 1. 1* ig. 3 is an inverted planview of one of the replacers or frogs. Fig. 4 is a verticalcross-section on the line 4 4 of Fig. 1. l ig. 5 is a similar section onthe line 5 5 of Fig. 1. Fig. 6 is a perspective view of one of the frogsor shoes, and Big. 7 is a similar view of the other frog or shoeconstituting my carreplacer. Fig. 8 is a plan view illustrating thelocal relation of the front wheels of a cartruck to the replacing frogsor shoes when the latter are placed in due position for effectingreplacement of the truck on'the rails. rigs. 9, 10, and 11 arecrosssections on the lines 9 9, 10 10, and 11 11 of I ig. 8.

'lhe two frogs or shoes constituting my car-replacer are indicated,respectively, by the letters A B. Each of them is constructed with twolaterally-diverging wings, or, in other words, each is double-winged,and each is provided with a lengthwise recess or groove 1 (seeespecially Figs. 2, 3, 6, 7) for receiving the head or body of atrack-rail x. In other words, each of the frogs A B is adapted to beplaced upon a rail, and it extends downward on each side of the rail, soas to rest upon the ties. At the corners of the winged portions on bothsides of the rail recessed lugs 2 are provided for receiving spikes 3,by which the frogs are secured in under side with spikes or teeth 4,(see Figs. 4, 5, 6, and 7,) which in practice enter the ties, and thusserve also to hold the frogs in place. In many cases these teeth may bealone sufficient for the purpose; but for entire safety spikes may alsobe used.

In view of their oiiferences of construction and for convenience ofdescription the device A may be termed the conical frog and the other,B, the concave frog. As shown best in Figs. 1 and 7, the conical frog Ahas two wings 5, that diverge from each other on one side at an angle ofabout forty-five degrees, and a rib 6 is formed along the middle of eachwing 5, practically in a horizontal direction. i he upper edge 7 of thetwo wings 5 5 is curved abruptly or is nearly vertical, as shown, andthus constitutes a turning flange, which coacts with the tread of thecar-wheel, as will be presently explained.

The frogB has laterally-extending wings 5 and a concavity 6 at the pointwhere the rib 6 appears in the frog A. The rim or edge 7 a of the frogBcorresponds in shape and position to the flange 7 of the frog A. 'ihatportion of the conical frog A which is on the opposite side of the railfrom the divergent w ings 5 is provided with a lengthwise groove 8, which extends parallel to the rail. The ends of this grooved portion,which for convenience may be termed the bridge portion or section,slopes down to the base of the rail and to the ties, upon which itrests. 'ihe portion of frog B corresponding to the groove 8 is indicatedat 8 in 1* ig. 11. A vertical flange or rib 9 extends along the side ofthe bridge portion of the frog B, the same being parallel to theadjacent rail. The grooves 10, formed in the ends of this bridgesection,turn inward at their upper ends, as illustrated in I igs. 1, 2, and 6,for a purpose that w ill be presently explained.

I w ill now describe the operation of replacing a car-truck by means ofmy invention.

Suppose a car to have been derailed so the front wheels of the truck arein the position indicated in Fig. 8, one wheel being between the rails03 and the other outside one of the rails. In such case the frogs A Bare placed and secured as close as practicable to the wheels. 'ihen,traction being applied to the truck, the wheels advance, and the leftwheel 2 first comes into contact with the conical frog A. In otherwords, the edge of the place. The frogs are also provided on the l treadof the wheel strikes upon the convex portion 6 of the frog; but theflange of the other wheel 2 strikes the concave portion 6 of the part B.This relative position of the Wheels with the frogs and. the contact ofone of them with the frog A are illustrated in Fig. 9. The angle orinclination of the wing and the convexity 6 with which the tread of thewheel 2 is in contact has the effect as the truck advances of forcingsaid wheel later ally, so that in the position illustrated in Fig. 10the flanges of both wheels 2 2 are in contact with the respective frogsand both have been forced and moved laterally toward the rails. The nextstep in the progress of replacement of the truck is illustrated in Fig.11, where the flange of the left wheel 2 is directly over the tread ofthe adjacent rail 0; and the flange of the other wheel 2 is in thegroove or depression alongside the head of the adjacent rail 0;. In thefinal step (not illustrated) the flange of the left-hand wheel 2 runsobliquely across and enters the groove 8, before described, whichextends along the top of the bridge or inner portion of the frog A andby which it is guided so that the tread of the wheel as it leaves thefrog A strikes up on the rail in normal position. While the left wheel 2makes this movement the other wheel 2 slides laterally in like degree,flllil the groove 8' guides the flange of the wheel so that the treadthereof passes on the adjacent rail. i'hus the front wheels of the truckare replaced, and it is obvious that the rear wheels of the same truckwill follow the front ones and be replaced in the same manner. Thedotted lines, Fig. 8, indicate another position of the truck-w reels,which may be called a position opposite that illustrated by full lines.In this case the flange of the right-hand wheel 2 is in contact with thebridge-section of the frog B, and upon applying traction thewheel-flange will run up in the curved groove 10, while the tread of theother Wheel 2 will run up upon the smooth portion of the bri;lgesectionof the frog A. The inward curve of the groove 10 will carry the flangeof the right-hand wheel 2 over into the groove 8 (see Figs. S and 11,)and the flange of the left-hand wheel 2 will pass over the groovedportion 8 of the frog A, and thus both wheels will be guided in properposition upon the rail. It w ill be noted that the bridge-section of thefrog A is cut away or grooved at 11 (see Figs. 1, 7, 8) to allow theflange of the wheel 2 to take the course described in replacing thetruck.

In Fig. 3 I illustrate a reinforce for the wings of the frogs, the sameconsisting of ribs 12, cast or otherwise formed on the under side of thewings. This construction strengthens the wings, while addinginapprociably to the weight and cost of the device.

It is of course to be understood that by constructing each frog with twoduplicate and divergent wings the frog is adapted foruse incar-replacing from either direction, and, further, this constructiongives the frog a broader base or hearing on the ties.

It will be noticed that my car-replacers will not interfere with any ofthe wheels that are on the rail. In other words, they can be placed infront of a train that has no wheels oil the track, such train passingover them without any interference. The replacers may be applied torails of different sizes, and it will be found that a pair of replacersthat will work efficiently on a thirty-pound rail may also be used toadvantage on a hundredpound rail but in practice it will be foundadvisable to make them any size best adapted to the weight of the railfor which they are especially intended, and in no case should it benecessary for a railroad to have more than two sizes.
